Questions

What inflation rate should I assume?
The U.S. averaged 2.52% a year over the last 30 years. The Federal Reserve targets 2%. Many retirement planners use 2.5% to 3%.
How much will $100,000 be worth in 20 years?
At 2.5% inflation, you would need $163,862 in 20 years to buy what $100,000 buys today. Put another way, $100,000 then will buy what $61,027.09 buys now.
What is the rule of 72?
Divide 72 by the inflation rate to estimate how many years it takes prices to double. At 3% a year, prices double in about 24 years.
